Thank you so much for the kind words! It's wonderful to hear that we handled the child portion of the game well so far ^^.
Facial hair will be an option for the MC later in the game. It's not currently a possibility for Cove. That's because facial hair doesn't end up working out the same as adding other types of optional layers. With regular hair, for example, you can just layer it over the head of the base sprite and it’s done. But facial hair has to fit with all of Cove’s different mouth expressions. From tiny frowns to being wide open. We’d need lots of different shaped facial hairs that switched out with Cove’s changing expressions to make sure the mouth was never awkwardly fitting with the facial hair. It’d be a lot of extra work and we aren't able to manage that right now.
I'm sorry. If the game gets enough support we could potentially make it happen, but it's not something I can guarantee.
